Total control & automation offers single-phase vector inverter, n50 series. Features: vector inverter for single phasing input only - high torque of 200 per cent or greater at speeds as low as 1 hz during starting and operation; realise triples driving by adding current suppression - stable operation even under the instantaneous impact load and overload is realised through the addition of overcurrent level adjusting function; maintains constant speed even at the time of sudden load change by rapid speed restoration characteristics; applicable to the transfer machine, treadmill, industrial washing machine due to its function of momentary current suppression; possible to select various operation methods - it is possible to select the operation method of either rs485 communication driving or analogue signal driving for the user`s convenience; compact size for easy installation - reduction in cubic volume, 52 per cent compared to the n100 series.
